Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80028, here are decompositions:
- 7 + 80021 = 80028
- 29 + 79999 = 80028
- 31 + 79997 = 80028
- 41 + 79987 = 80028
- 61 + 79967 = 80028
- 89 + 79939 = 80028
- 127 + 79901 = 80028
- 139 + 79889 = 80028
Showing the first eight; more decompositions exist.
